ELECTRICAL BECEPTACLE FOR CONDUIT OUTLET-BQXES.

Specification of Letters Patent.

Patented Feb. so, rare.

Application filed December 27, 1910. Serial No. 599,354.

To all whom it may concern:

Be it known that I, CARL H. BISSELL, of Syracuse, in the county of Onondaga and State of New York, have invented a new and useful. Electrical Receptacle for Conduit Outlet-Boxes, of which the following is a specification.

This invention has for its object the production of an electrical receptacle adapted to be used in connection with conduit outlet boxes; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views. v t

Figure 1 is a longitudinal sectional view through a conduit outlet box provided with one form of my invention.

Fig. 2 is a transverse sectional view through the receptacle, the contiguous portion of the wall of the conduit outlet box supporting the receptacle being also shown.

Fig. 3 is a plan of the base of the recep- 'tacle.

Fig. 4 is an inverted plan of one form of cap for the base.

Fig. 5 is a sectional view through the cap, taken at a right angle to the section thereof shown in Fig. 2.

Fig. 6 is an elevation of a receptacle provided with another form of cap, the adjacent portion of the supporting wall of the conduit outlet box being also shown.

Figs. 7 and 8 are, respectively, a plan and an inverted plan of the cap shown in F ig. 6.

This invention is particularly adapted for with an electric conduit outlet box formed with a passage in one wall thereof, and comprises generally a receptacle extending into the box through the passage and having terminalsv for connection with the wires in the box and for connection with an electrical appliance, the receptacle having means for coacting with the margin of the wall around such passage whereby the rece 'itacle is supported by such wall] 1 is the conduit outlet box having an opening in one side thereof, and. a removable wallv 2 serving as a cover for such opening, such wall 2 being formed with a passage 3 therein. The box 1 is also formed with suitable means, as nipples 4, for connection with the conduits, as the conduit 5, through which the wires 6 enter and leave the box.

The removable wall 2 is secured to the box in any suitable manner, as by screws 7, extending through the wall 2 and'threading into lugs provided on the box, as the lugs 8.

The receptacle comprises a base 9, a cap 10 and means for clamping the base and cap together and also'secnring the receptacle to the removable wall 2; the base 9 being located in the box and having terminals for connection with the wires (3 in the box, and the cap having terminals for connection with the terminals on the base and with an electrical appliance, the cap 10 closing the passage l, and the base 9 and the cap 10 having surfaces arranged on opposite sides of the n'largin 11 of the wall 2, around the passage 3.

As here shown the base is circular in form and is formed with a substantially flat sur face 12 opposed to the passage 3 and upon which terminals 13 are n'iounted, for connection with the wires (3, and with diametrically disposed segmental peripheral projections or guides 14: projecting from the surface lzwtoward the passage3 and. terminating near the margin 11 of the wall 2 around the passage 3. The base is also formed with other diametrically disposed projections 15 arranged midway between the projections or guides 14 and serving to space the wires 6 connected, respectively, to the terminals 13. The side edges of the projections 15 diverge from the side edges of the projections 14; toward the free ends of said projections 15 for forming between the projections 1-l and lo ire-receiving spaces opening through the periphery of the base and increasing in width toward the free ends of the projections llv and 15. Said terminals 13 extend in opposite directions from a diameter of" the base extending in the direction of the wires (3 and are located on op|' ositc sides of the diameter intersecting the iirst-i'nontioned dianwtor at a right angle; and the terminals l are provided with binding devices located close to the projections 01' guides 14. Such binding devices consist of clamping screws 16 which coact with lips'17 provided on the terminals 13. The terminals 125 are sccuredto the surface 12 by screws 18 extending into the base from the rear side thereof.

The base 9 is unprovided with means for securing it directly to the box 1 and usually thewires 6 are pulled out of the box, stripped of insulation and secured to the terminals 13, and the base and cap are then clamped to the removable wall 2, as hereinafter explained, prior to the placing of such wall in position.

The cap supports terminals 19 adapted to be connected respectively to the terminals 13 and is formed with a reduced portion 20 extending through the passage 3 and between the guides or projections 14 to a point near the free' ends of the projections 15. The cap is also provided with a flange 21 lapping the outer face of the margin 11 of the wall 3 around the assage 4, and c0- acting with the end surfaces of the projections or guides 14 for securing the receptacle in position. The projections or guides 14 and reduced portion 20 are provided with interfitting means, as teno s 14 and mortises 20 the tenons 14 e tending lengthwise of the inner faces of the projections 14 midway between theirside edges and projecting inwardly from said faces, and the mortises or grooves 20 extending length- Wise of the periphery of the reduced part 20 of the cap 10. The opposing surfaces of the flange 21 and the projections or guides 14 and the contiguous part of the periphery of the portion 20 form a groove for receiving the margin 11 of the wall 2. Usually a Washer 22 is interposed between the flange 21 and said margin 11.

The base and cap are clamped together by screws' 23, the screws also serving to clamp the base and cap on the margin 11 of the wall 2 and also to electrically connect corresponding terminals 13 and 19. In Figs. 1 to 5 inclusive the cap is in the form of a rosette and the terminals 19 are connected to wires 24 to which a drop lamp 25 is connected, such terminals 19 being shown as provided with binding screws 26 cooperating with lips 27 similar tb the screws 16 and lips 17 of the terminals 13.

The terminals 19 are shown as secured to the cap 9 by hollow screws 28 arranged in passages 29 in the cap and the clamping screws 23 extend through the hollow screws 28. The wires 24 connected to the terminals 19 extend through a suitable coupling 30 arranged axially 01 the cap.

. However, as seen in Figs. 6, 7 and 8 the cap may be provided with another arrangement of terminals, it being shown in Figs.

6, 7 and 8 as a lamp socket and as having an outer or sleeve terminal 31 and an inner or central terminal 32, the sleeve terminal 31 being held in position by an arc-shape clamping piece 33 resting on ledges at the bottom'of the sleeve 31, and the base and cap being clamped together by screws 34 extending through the piece 33 and the central terminal 32 and threading into the terminals on the base.

The terminals 13 of the basehre provided with two sets of screw holes 35, 36, one set as 35 of which are spaced apart proper distance to receive the screws 23 and the other set as 36 being spaced apart proper distance to receive the screws 34.
